 /**
  * An interface for an adaptable object.
  * <p>
  * Adaptable objects can be dynamically extended to provide different
  * interfaces (or "adapters"). Adapters are created by adapter
  * factories, which are in turn managed by type by adapter managers.
  * </p>
  * For example,
  * <pre>
  * IAdaptable a = [some adaptable];
  * IFoo x = (IFoo)a.getAdapter(IFoo.class);
  * if (x != null)
  * [do IFoo things with x]
  * </pre>
  * <p>
  * This interface can be used without OSGi running.
  * </p><p>
  * Clients may implement this interface, or obtain a default implementation
  * of this interface by subclassing <code>PlatformObject</code>.
  * </p>
  * @see IAdapterFactory
  * @see IAdapterManager
  * @see PlatformObject
